Portland, Maine Historic Fort Tours and Harbor Cruises


Featured Casco Bay Boat Cruises

About Us

Centuries ago, seafarers landed on the shores of Maine from rough waters leagues beyond.

We can only imagine how much of what they found took their breath away.

Today, we continue to be spoiled by the beautiful waters of Casco Bay and the views and experiences that abound here. There really is nothing like it.

SeaPortland brings you straight into the heart of authentic Maine.

Aboard the Elizabeth Grace and other vessels in our fleet, we show you the parts of Casco Bay unseen by most. We provide experiences that strike at the heart of what makes this part of the world so magical.

Join us for boat tours of previously unexplored early nineteenth-century forts. Bathe in the warm lights of a summer sunset over the water. Breathe in the ocean air while viewing Maine’s famous lighthouses. Toast local craft beverages. What could be better?

Join us for a tour today.
